I agree! It was a PBS program called African American Lives by Henry Louis Gates Jr. author, educator, historian, ect... I don't know about Danny Glover, but Don Cheadle has descendants from Tishamingo, Oklahoma. He is of Chickasaw freedmen descent. I believe there might even be a Cheadle street down in Tish. There is a really big Cheadle family in Oklahoma. Gates also has another African American Lives II due to air next month on PBS.
